Grouping The Related (Scifi) Skin Lines

So to preface this I am a ridiculous scifi nerd, and love pretty much all such things (except comics; never got on with those). With the reveal of the Odyssey Skin Line ( FINALLY GET'S A SKIN AND IT'S ALL I COULD ASK FOR), there are some lines from Rhaast (portraits for Kayn forms please) that reveal him as a Dark Star creation; therefore all Odyssey skins and Event Horizon (Dark Star and Cosmic) skins are from the same Universe. Now at least one other skin has a special line for the Dark Stars, and it's Gun Goddess , which would put the Steel Valkyries Line into the same Universe as well. It would be awesome to see which other Skin Lines tie into this Universe, or link together to form others. Are the Star Guardians also in this reality? Are the Mecha and PROJECT Lines connected in some way, maybe linked by Program (thanks to we know the PROJECT and Program certainly are)? I can't think of any non-scifi Lines that might be linked that aren't already (e.g. Beastslayer and Prehistoric), but I'm sure there are some. (especially because this might lead to further stories...)
